Arterial occlusive disease can be prescribed oral aspirin, dipyridamole, prostaglandin E1, atorvastatin and other drugs. Arterial occlusive disease, or atherosclerotic occlusive disease, is atherosclerosis of the arterial lining, intima-media degeneration or calcification, and secondary thrombus formation in the lumen, which ultimately leads to narrowing of the lumen of the blood vessel, or even occlusion. Multiple arterial vessels throughout the body can be diseased, and the cause of the disease is closely related to hyperlipidemia, hypertension, smoking, diabetes, and so on. Pharmacological treatments include lipid-lowering and plaque stabilization (atorvastatin), improvement of hypercoagulability/antiplatelet aggregation (aspirin, dipyridamole), vasodilatation and promotion of collateral circulation (prostaglandin E1), and can be combined with hyperbaric oxygen therapy. Surgical treatment is feasible to reconstruct arterial access if necessary. When arterial occlusive disease occurs, it is recommended to seek prompt medical treatment, and the use of drugs should be under the guidance of a specialized doctor.
